Hi Gents
This may be a duplicate of an email already sent, however I may have
sent it to the wrong email address, so here is my plea again.
I have just put a Argosy 525d on the bench, TX is fine on tune and cw,
50 watts at full power or 5 watts with rear switch in low position, the
reported problem is no TX audio on SSB, tried another mic, still the
same.
Looking at the diagram I see mic audio goes thru' a 4558 I/c, are they a
known problem or should I look elsewhere, going to do voltage checks
Wednesday.
Have any of learned gents met this problem, if so what did you find.
Stay well and healthy
